South Australian police are warning the public about the dangers of riding motorcycles at high speeds. One rider, in particular, filmed his own devastating motorcycle crash. The rider was traveling at speeds over 160 mph when he collided with a stopped truck. The accident left him in a coma for two months and with permanent brain damage when he woke up. He will have to live under family care for the rest of his life. Please, be careful when you're out on the road, this kind of outcome isn't worth it.
